I've read the entire DMT thread that was posted above, and I feel more confused than ever. I think my problem is that I just don't know the procedural basics of combining an MAOI with DMT, so reading everyone's personal experiences has left me feeling like I'm not sure what would be practical for me.
Seems like the traditional ayahuasca brew produces the best results visually, but has the most potential for purging. I've heard from ayahuasca-ites that this purging is a normal part of the spiritual experience, as it purges negative energy. But to be honest I don't really care. The less purging the better.
I think I would go with b. caapi as the DMT source as oral DMT seems to be the most potent, but for an MAOI inhibitor I am just not sure.
